The Causal Agents of Urinary Tract Diseases are Often Members

Question

The causal agents of urinary tract diseases are often members of the normal flora.

Accepted Answer

This statement is true as urinary tract infections (UTIs) are often caused by bacteria from the individual's own normal flora, such as Escherichia coli, Klebsiella, and Proteus species. These bacteria can ascend the urinary tract from the urethra to the bladder and even to the kidneys, causing UTIs. However, there are also cases where UTIs are caused by pathogenic bacteria that are not normally found in the urinary tract.
